Mark Price Discrepancy

Mark price discrepancy refers to the difference between the index price of an asset and the actual trading price on a specific exchange or derivative platform. The index price is usually a volume-weighted average of prices across multiple exchanges to reflect the true market value.

The mark price is used by derivatives platforms to calculate unrealized PnL and trigger liquidations. If a platform's mark price deviates too far from the index price, it can cause unfair liquidations or allow for arbitrage opportunities.

This often happens due to temporary liquidity droughts or manipulation on smaller exchanges. Maintaining a tight alignment between these prices is vital for market fairness.

Protocols often use funding rate mechanisms to pull the mark price back toward the index price. Discrepancies are a primary indicator of market inefficiency and potential manipulation.
